A glutinous rice environment-friendly starch type adhesive and a preparing process thereof are disclosed. The adhesive comprises following raw materials by weight: 55-110 parts of glutinous rice flour, 40-60 parts of chloroprene latex, 30-55 parts of synthetic resin, 1-10 parts of an additive and 1-8 parts of an auxiliary agent. The adhesive is prepared by cleaning and soaking the glutinous rice flour, adding deionized water into the glutinous rice flour, cooking the mixture until slurry is formed, filtering the cooked glutinous rice flour to obtain a glutinous rice adhesive precursor, mixing other raw materials, adding deionized water into the raw material mixture, fully stirring the raw material mixture, then adding the precursor into the raw material mixture, and heating and stirring the obtained mixture. The adhesive is an efficient water-soluble adhesive, and has advantages of no toxicity, capability of being non-combustible and environment-friendly, rapid drying, high initial adhesive force, good heat resistance, good ageing resistance, and the like. The adhesive is suitable for manufacturing furniture, office chairs, mattresses, sofas, pillows and other soft furniture, and for manufacturing automotive trim, bags, suitcases, and leather products, and can be used for adhering various polar water-absorbing materials. According to the adhesive and the process, the adopted raw materials are simple, the preparing process is easy to operate and control, the production cost is low and the adhesive and the process are suitable for large-scale production.
